Compute nt zeros of Bessel function Y0(z), and derivative at each zero.

The derivatives are given by Y0’(z0) = -Y1(z0) at each zero z0.

Parameters:

nt : int

Number of zeros to return

complex : bool, default False

Set to False to return only the real zeros; set to True to return only
the complex zeros with negative real part and positive imaginary part.
Note that the complex conjugates of the latter are also zeros of the
function, but are not returned by this routine.
